Less than 5000 years ago, northern europeans developing a genetic mutation that allowed them to digest cow’s milk.

But then how do other non-European groups like Middle Easterners and Asians drink it normally? Did they independently evolve the same mutation?

Fermentation (kefir, yoghurt, cheese). Recently lactase.

I’m no expert but I think it’s a mutation that still isn’t universal i.e. there is still a very large lactose-intolerant population in east-asia, which is also reflected in their cuisine.
